5 Claims.

The present invention relates to window .screens and means for mountingthe same, and .is particularly concerned with window screens for use inconjunction with penitentiaries, penitentiary hospitals, and variousother detention institutions of this character.

The primary object of the present invention is to provide a windowscreen and means for mounting the same whereby it cannot be removed byinmates of penal institutions, either to permit escape of the inmates orfor use as a weapon by said inmates.

Another object of theinvention is to provide a window screen andmounting means therefor of the character above mentioned and which isdesigned to be moved to different positions of adjustment for permittingaccess to the outside surfaces of adjacent windows for cleaningpurposes, without removal of the screen or providing an openingsufiiciently large to permit a person to pass through the windowopening.

With the above and other ends in view, the invention is more fullydisclosed with reference to the accompanying drawings, inwhich Figure lis a front elevation of a window and screen;

Fig. 2 is a section taken on the line 2-2 of Fig. 1;

Figs. 3, 4 and 5 are sections, similar to Fig. 2, illustrating differentpositions of the screen;

Fig. 6 is a fragmental front elevation, partly broken away and insection, and

Figs. 7 and 8 are horizontalsections taken on different planes.

Like characters of reference are employed throughout to designatecorresponding parts.

A metal window sash l is provided with the usual vertical and horizontalbars supporting the window glass, the latter being permanently mountedin the sash. Such sashes usually have openings provided for purposes ofventilation, and in the embodiment shown two openings are provided. Eachopening is designated 2 and has a frame 3, also of metal, secured to thesash adjacent thereto, and an auxiliary sash 4 is pivoted at 5 in eachframe so that it may be swung to open or closed position.

A screen frame 6, preferably formed of steel and solidly welded at thecorners, has a wire mesh 1 secured thereto. Adjacent the lower edge, oneach side of the screen frame, is a bottom tilt control bracket 8 eachcarrying a pin 9, and adjacent the upper edge, on each side of thescreen frame, is a top tilt control bracket l each carrying apin ll.Secured to the lower rail l2 which defines the opening 2 are twohook-like brackets 13 adapted to engage the pins 9 on respective bottomtilt control brackets. Secured to the upper rail M which defines theopening 2 are two stationary brackets IS with L-shaped slots [6 therein,said brackets I being disposed with one adjacent each of the top tiltcontrol brackets l0, whereby the pins I I may cooperate with the slotsiii in a manner hereinafter to appear. Also secured to the rail i2 are,two bottom clips l1, and to the top rail 14 are two top clips H3.

The closed position of the screen may best be seen in Fig. 3, whereinthe lower edge of the frame 6 rests upon the bottom clips ll. In orderto hold the screen in this position, set screws l9 carried by extensions20 on the brackets l5 are tightened into engagement with respective tiltcontrol brackets. The set screws are, preferably, of the Allen typescrews in order that they can- .not be loosened by means of a coin,nailfile or like article.

The screen mounting means above described permits the screen tobe movedto two tilted positions. The lower edge of the screen may be swungoutwardly while the upper edge is retained, or the upper edge may bemoved outwardly while the lower edge is retained. Such operations willnow be described in detail.

If the loweredge is to be swung outwardly, the set screws l9 areloosened, and the screen is bodily shifted upwardly, as shown in Fig. 4,un- .til the pins 9 are .at a height higher than the hook-like bracketsI 3. When the screen is so positioned, the upper edge of the screenframe engages the top clips I8 and the pins II are adjacent the mouth ofrespective slots IS in the stationary brackets 15. The screen frame 6 isthen swung to the position shown in Fig. 5, causing the pins II to enterthe slots l6, and as the pins drop into the angularly disposed legs oftheir respective slots they hold the screen in the tilted positionshown. The screen, when thus positioned, provides an openingsufficiently large to permit cleaning of the lower portion of theoutside window surface.

When the screen is to be tilted outwardly from the top, after looseningthe set screws 19 it is pushed outwardly. The lower edge of the screenframe rests in the clips I1, and as the upper edge swings outwardly thepins 9 are engaged by the hook-like brackets 13, which restrict theswinging movement.

With the screen in either of its tilted positions it cannot be removedwithout using suflicient force to destroy the parts thereof. In thisrespect the screen structure and its mounting mechanism is madestructurally strong and rugged, in order that it may withstand forcesthat might be exerted without levers or implements for prying partsthereof loose. Of course, such levers or implements which might be usedfor prying are not ordinarily available to inmates of institutions inconjunction with which the invention is designed to be used.

Although a specific embodiment of the invention has been illustrated anddescribed, it will be understood that various changes may be made withinthe scope of the appended claims without departing from the spirit ofthe invention, and such changes are contemplated.

What I claim is:

1. In combination with a window opening frame, a screen, retaining clipsat the top and bottom of said frame, the lower edge of the screen beingnormally disposed in the lower clips and.

the screen and clips being proportioned whereby the upper edge clearsthe upper clips for outward swinging movement, means rendered operativeby outward swinging movement of the upper edge of said screen forpreventing removal of the lower edge of said screen from said lowerclips, said screen being movable vertically from its normal positionwhereby the upper edge thereof engages said upper clips and the loweredge thereof clears said lower clips for outward frame, a screen,retaining clips at the top and bottom of said frame, the lower edge ofthe screen being normally disposed in the lower clips and the screen andclips being proportioned whereby the 'upper edge clears the .upper clipsfor outward swinging movement, means rendered operative by outwardswinging movement of the upper edge of said screen for positivelyrestricting outward swinging of the lower edge ofsaid screen, saidscreen being movable to position its upper edge in said upper clipswhereby its lower edge clears said lower clips for outwardswingingmovement, and means rendered operative by outward swinging movement ofthe lower edgeof said screen for positively restricting such swingingmovement. 3. In combination with a window opening frame, a screen,retaining clips at the top and bottom of said frame, the lower edge ofthe screen being normally disposed in the lower clips and the screen andclips being proportioned whereby the upper edge clears the upper clipsfor outward swinging movement, means rendered operative by outwardswinging movement of the upper edge of said screen for positivelyrestricting outward swinging of the lower edge of said screen, saidscreen being movable to position its upper edge in said upper clipswhereby its lower edge clears said lower clips for outward swingingmovement, and means rendered operative by outward swinging movementofthe lower edge of said screen for positively restricting such swing ingmovement, said last named means including means for holding the screenin a tilted position.

4. In combination with a window opening frame, a closure for normallycovering the opening, cooperating means on the frame and said closureabove the center of the latter for. supporting the lower end of theclosure in an outwardly swung position from the frame, and

cooperating means on the frame and said closure below the center of thelatter for supporting the upper end of the closure in an outwardly swungposition from the frame, said closure being movable toward and thenslidable along the frame in order to disengage one set of saidcooperating means for one of said outwardly swung positions of saidclosure to engage the other set of said co-operating means for the otherof said outwardly swung positions of said closure.

5. In combination with a window opening frame, a closure for normallycovering the open-,

ing, cooperating means on the frame andsaid closure above the center ofthe latter for supporting the lower end of the closure in an outwardlyswung position from the frame, cooperating means on the frame and saidclosure below the center of the latter for supporting the upper end ofthe closure in an outwardly swung position from the frame, said closurebeing movable toward and then slidable along the frame in order todisengage one set of said cooperating means for one of said outwardlyswung positions of said closure to engage the other set, of saidcooperating means for the other of said outwardly swung positions ofsaid closure, andmeans on the frame independent of said cooperatingmeans for limiting the outward swing of either of said ends of saidclosure.
